BACKGROUND OF THE INVENTION

The invention relates to a storage box for CDs, computer disks, cassettetapes and like mass information carriers, comprising a box part, atleast one drawer part, and spring means and locking means associatedwith the or each drawer part, the or each drawer part being arranged forreceiving the mass information carrier and being slidably receivable,via a drawer opening, in the box part, the spring means associated withthe or each drawer part being arranged for pressing the relevant drawerpart into an at least partially opened position, the locking meansassociated with the or each drawer part being arranged for holding therelevant drawer part in a closed position against the action of thespring means; the box part, the drawer part, the spring means and thelocking means all being manufactured in an injection molding process, atleast partly from synthetic material, the box part being manufacturedfrom at least one molded part, the drawer part being manufactured fromone molded part, the spring means and the locking means forming anintegral part of one or more of the molded parts mentioned and hencebeing formed integrally with these molded parts during the injectionmolding process, the locking means forming an integral part of both themolded part comprising the drawer part and the at least one molded partcomprising the box part.

Such storage box is known from international patent application WO87/05884. On page 11, lines 27-32 of this publication, it is describedthat the spring 86 can be an integral part of the drawer part or the boxpart. Hence, from this publication, a skilled person may learn that thenumber of parts of which the storage box is manufactured, can be limitedby designing the spring as an element formed integrally with the moldedparts. The drawings of this publication directly make it clear that thisalso holds for the locking means.

A drawback of the known publication, however, is formed by theconstruction of the locking means. The drawer part of the known storagebox can only be opened with one hand when a single storage box is takenin the hand. When a box located in a stack is to be opened, theleft-hand side of the stack should be freely accessible for operatingthe locking means. In practice, however, usually more stacks of storageboxes are disposed side by side. Under those circumstances, the knownstorage box can only be opened when the storage box is removed from thestack. This is particularly inconvenient.

European patent application EP-A-0 568 729 discloses another storagebox. The drawback of the construction known from that publication isthat it consists of a large number of parts, to be manufacturedseparately. After the manufacture of these separate parts, the differentparts of the storage box have to be assembled, which operation can beperformed only manually. The manufacture of the large number of separateparts and the assembling operations have as a consequence that the costprice of the known box is too high, on which account it has not foundwidespread application in the market. Another drawback of the known boxis that the unlocking means are operated by a separated unlocking buttonwhich occupies a considerable amount of space next to the drawer part.Not only does this disturb the outward appearance of the storage box,but the storage box is moreover considerably larger than the dimensionsof the mass information carrier to be stored would require.

SUMMARY OF THE INVENTION

The object of the invention is to provide a storage box for massinformation carriers of the type mentioned in the preamble, whichstorage box has the advantages of the known storage box, i.e. built upfrom few parts, and in which the drawbacks of the known storage box areovercome. The intended storage box must be capable of being manufacturedin an economical manner and, moreover, must have an elegant outwardappearance. The space occupied by the locking means must be minimal.

To this end, according to the invention, the storage box of the typementioned in the preamble is characterized in that the locking meanscomprise at least one locking assembly, each locking assembly comprisinga locking projection, an unlocking projection, a release projection, aspring lever, a first projection, a second projection and a retainingprojection, the locking projection, the unlocking projection and therelease projection forming a part of the at least one molded partcomprising the box part, the first projection and the second projectionbeing connected to a free end of the spring lever, which spring lever,together with the retaining projection, forms part of the molded partcomprising the drawer part, the first projection being arranged forcooperating with the locking projection and the unlocking projection,the second projection being arranged for cooperating with the releaseprojection and the retaining projection, in a closed position, the firstprojection being caught behind the locking projection, wherein foropening the drawer part the spring lever being pressed into an obliqueposition in that the first projection strikes the unlocking projection,the second projection thereby catching behind the retaining projection,enabling the first projection, in the slide open movement of the drawerpart, to pass the locking projection, the second projection striking therelease projection after the first projection has passed the lockingprojection, causing the second projection to be pressed from theretaining projection and allowing the spring lever to resume itsoriginal position.

Such storage box may have exactly the same dimensions as theconventional CD boxes, which are provided with a cover part which ispivotally connected to a bottom part. The locking means may beincorporated behind the drawer part, adjacent the sidewall locatedopposite the drawer opening. This enables the storage box according tothe invention to be stored in the existing storage systems. Due to theconstruction of the locking means, entirely integrally formed with themolded parts from which the storage box is built up, the drawer can beopened by pressing the front side of the drawer. Hence, the opening andclosing of the drawer part can be effected in a particularly simplemanner. Even when the storage box is arranged in several stacks side byside, a storage box from the stack can be opened with one hand withoutthe storage box having to be removed from the stack. Since the lockingmeans are completely accommodated in the interior of the storage box,the storage box according to the invention moreover has an elegantoutward appearance.

Preferably, the number of molded parts for the box part is kept to aminimum, i.e. one molded part. However, in view of the injection moldsbeing withdrawable, it may be necessary that the box part be built upfrom two or more molded parts. In general, the drawer part can beassembled from one molded part. For the sake of the assembly of thestorage box, the molded parts of the box part can readily be snappedtogether. The final assembly is effected by sliding the molded partcomprising the drawer part into the drawer opening. After this finalassembling operation, which can readily be automatized, the storage boxis ready for use. Hence, the storage box according to the invention canbe manufactured in a very inexpensive manner. The phrase ‘at leastpartly’ in the claim relates to embodiments wherein, in the injectionmolding process, a for instance metal spring is embedded in the plastic.This does not lead to additional assembling operations, because themetal parts form an integral part of the relevant molded part.

Further elaborations of the storage box according to the invention aredescribed in the subclaims and will hereinafter be further explained onthe basis of two exemplary embodiments, with reference to theaccompanying drawings.

Because known set-up devices for mass information carriers are generallyintended for boxes having a pivotable cover, the set-up devices thereforare of such design that the storage boxes have to be removed from theset-up device in order to be capable of being opened. As a result, thestorage boxes keep lying around somewhere near the playback equipmentand are not placed back in the set-up device. Another drawback of theknown set-up devices is that the boxes are generally positioned inparallel relationship next to or above each other. As a consequence,only the text printed on the narrow lateral sides of the storage box isreadable to the user. The text on the top and bottom sides of thestorage box can only be read when the storage box is removed from theset-up device. International Publication number WO93/15978 discloses aset-up device for magnetic discs which are not each accommodated in astorage box. However, the principle of pivotably storing the massinformation carriers provides the user with the possibility of leafingthrough the different mass information carriers without these massinformation carriers having to be removed from the set-up device.

The object of the invention is to provide a set-up device for storageboxes without the above-described drawbacks.

To this end, the invention provides a set-up device comprising storageboxes according to the invention, which storage boxes each comprise atop and a bottom side and four lateral sides, while the thicknessrelative to the length and width of the top and bottom sides of thestorage box is relatively slight, the set-up device further comprising abase disposable on a horizontal surface or connectable to an inclined orvertical surface, the base comprising means for clamping a number ofstorage boxes adjacent the lateral side thereof opposite the draweropening, the means for clamping being so designed that a clamped storagebox is pivotable relative to the base, with the imaginary pivot line ofthe pivotal movement extending parallel to and lying adjacent orcoinciding with the lateral side located opposite the lateral sidecomprising the drawer opening.

Such set-up device provides the user the possibility of leafing throughthe different storage boxes without these boxes having to be removedfrom the set-up device. During this leafing operation, the user can readthe text printed on the top and bottom sides of the respective storageboxes. Moreover, because the storage boxes comprise a drawer, thestorage boxes need not necessarily be removed from the set-up device inorder to take the mass information carrier from the storage box. Indeed,the storage box can be opened while it is still located in the set-updevice. Hence, the set-up device according to the invention will nolonger involve storage boxes being spread and getting mislaid.

Further elaborations of the set-up device according to the invention aredescribed in the subclaims and will hereinafter be further explained onthe basis of an exemplary embodiment, with reference to the accompanyingdrawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Presently, with reference to FIGS. 1-3, two exemplary embodiments of astorage box for CDs, computer disks, cassette tapes and like massinformation carriers will be described first. The storage box of FIG. 1comprises a box part 1, 2, at least one drawer part 3, spring means 4and locking means 5 associated with the drawer part 3. The or eachdrawer part 3 is arranged for receiving the mass information carrier andis slidably receivable in the box part 1, 2 via a drawer opening 13. Thespring means 4 associated with the or each drawer part 3 are arrangedfor pressing the drawer part 3 into an at least partially openedposition. The locking means 5 of the drawer part 3 are arranged forholding the relevant drawer part 3 in a closed position, against theaction of the spring means 4. The box part 1, 2, the drawer part 3, thespring means 4 and the locking means 5 are all manufactured from plasticin an injection molding process. In the present exemplary embodiment,the box part 1, 2 is manufactured from two molded parts V1, V2. Thedrawer part 3 is manufactured from one molded part V3. The spring means4 and the locking means 5 form an integral part of one or more of themolded parts V1, V2, V3 mentioned and are hence integrally formed withthese molded parts V1, V2, V3 during the injection molding process.Although in the exemplary embodiment shown in FIG. 1, the box part 1, 2is manufactured from two molded parts V1, V2, viz. a bottom part 1 and acover part 2, it is also within the framework of the invention when thebox part 1, 2 is manufactured from a single molded part. In view of theinjection mold being withdrawable, two molded parts are opted for in thepresent case. According to the invention, a smallest possible number ofparts should be aimed at so as to minimize the assembling operations.

The spring means 4 form an integral part of the molded part V3comprising the drawer part 3. In the present exemplary embodiment, thespring means 4 are designed as a thin circular or elliptic strip ofsynthetic material connected to the rear side 14 of the molded part V3comprising the drawer part 3. The elasticity of the plastic imparts acertain resilience to this strip, which resilience seeks to bring thestrip 4 into its original shape. In the closed position of the drawerpart 3, the plastic strip 4 does not have its original shape but iscompressed, causing it to exert a spring force on the drawer part 3.

As is clearly shown in FIGS. 1 and 2, the locking means 5 form anintegral part of both the molded part V3 comprising the drawer part 3,and the at least one molded part V1, V2 comprising the box part 1, 2.The locking means 5 comprise at least one locking assembly 5. Eachlocking assembly 5 comprises a locking projection 6, an unlockingprojection 7, a release projection 8, a spring lever 9, a firstprojection 10, a second projection 11 and a retaining projection 12. Thelocking projection 6, the unlocking projection 7 and the releaseprojection 8 form part of the molded part V1 comprising the bottom part1. The first projection 10 and the second projection 11 are connected toa free end of the spring lever 9, which spring lever 9, together withthe retaining projection 12, forms part of the molded part V3 comprisingthe drawer part 3. The first projection 10 is arranged for cooperatingwith the locking projection 6 and the unlocking projection 7, and thesecond projection 11 is arranged for cooperating with the releaseprojection 8 and the retaining projection 12. In the closed position,the first projection 10 is caught behind locking projection 6. When thedrawer part 3 is to be opened, the user should press against the frontside of the drawer part 3. This involves the spring lever 9 beingpressed into an oblique position in that the first projection 10 strikesthe unlocking projection 7. When the spring lever 9 is thus pressedleftwards, the second projection 11 catches behind the retainingprojection 12, enabling the first projection 10, in the slide-openmovement of the drawer part 3, to pass the locking projection 6. Afterthe first projection 10 has passed the locking projection 6, the secondprojection 11 strikes the release projection 8, causing the secondprojection 11 to be pressed from the retaining projection 12 andallowing the spring lever 9 to resume its original position. Hence, whenthe drawer part 3 is closed, the first projection 10 can catch behindthe locking projection 6 again for holding the drawer part 3 in itsclosed position. It will be understood that due to the complete absenceof operating buttons for unlocking the drawer part 3, the storage boxwith locking means as described hereinabove has a particularly nicelylined outward appearance. Moreover, the control is simple and theoperation is reliable.

The present exemplary embodiment of the storage box comprises twolocking assemblies 5, each located adjacent an end of a lateral side 14of the drawer part 3 opposite the drawer opening 13. This provides astable locking of the drawer part 3. It is observed that in theexemplary embodiment shown, the projections 6, 7, 8, 10, 11 and thespring lever 9 are all located in a horizontal plane. It is understoodthat an arrangement of these parts in a vertical plane is also possibleand also falls within the framework of this invention. Such arrangementmay be advantageous in a storage box having a number of drawer parts 3,as shown in FIG. 3.

In the exemplary embodiment shown in FIG. 1, the molded part V3comprising the drawer part 3 is also provided with an accommodationspace 15 for accommodating documentation belonging to the massinformation carrier, such as for instance an information booklet.

The exemplary embodiment shown in FIG. 3 differs from the exemplaryembodiment shown in FIG. 1 only in that the storage box comprises anumber of drawer parts 3. However, the locking means 5 and the springmeans 4 are of similar design. The box part 1, 2 is likewise composed oftwo molded parts V1, V2, the first molded part V1 being a substantiallytubular section 1 having drawer part guides 32 in the sidewalls thereof,and the second molded part V2 constituting a rear wall 2 of the storagebox.

FIGS. 4, 6 and 7 show an exemplary embodiment of a set-up deviceaccording to the invention. FIG. 5 shows an exemplary embodiment of astorage box 16 forming part of a set-up device according to theinvention. The set-up device shown comprises storage boxes 16 accordingto the invention for storing CDs, computer disks, cassette tapes andlike mass information carriers D. The storage boxes 16 have a top sideand a bottom side 17 and 18 respectively, and four lateral sides 19, 20,21, 22. The thickness of the storage box 16 relative to the length andwidth of the top and bottom sides 17, 18 of the storage box 16 isrelatively slight. The storage boxes 16 each comprise a box part 23 anda drawer part 24 which, via a drawer opening 25 at one of the lateralsides 19 of the storage box 16, is slidably received in the box part 23.The set-up device comprises a base 26 disposable on a horizontal surfaceA or connectable to an inclined or vertical surface A. The base 26comprises means 27 for clamping a number of storage boxes adjacent thelateral sides 22 thereof opposite the drawer openings 25. The means 27for clamping are so designed that a clamped storage box 16 is pivotablerelatively the base 26, while the imaginary pivot line L of the pivotalmovement extends parallel to and lies adjacent or coincides with thelateral side 22 located opposite the lateral side 19 comprising thedrawer opening 25. For this purpose, in the present exemplaryembodiment, each storage box 16 is provided with two circular recesses28, each located in a lateral side 20, 21 bounding the drawer opening25, adjacent the lateral side 22 located opposite the drawer opening 25.The base 26 is provided with at least two opposite, parallel base parts26 a, 26 b, between which a receiving cavity 29 is located, each basepart 26 a, 26 b being provided, on a side facing the receiving cavity29, with a series of pivot journals 27. Located opposite each pivotjournal 27 on one base part 26 a is a pivot journal 27 on the other basepart 26 b. Between each pair of opposite pivot journals 27, a storagebox 16 can be clamped in that each pivot journal 27 of a pair ofopposite pivot journals 27 can be brought into engagement with acircular recess 28, associated with that pivot journal 27, in therelevant storage box 16. In the shop, the mass information carriers willbe presented in storage boxes 16 provided with recesses 28 and at homeor at the company, they can be clamped or snapped in the base 26 of theset-up device. This prevents the storage box from becoming astray, whilethe main surfaces can nevertheless be properly inspected when thedifferent storage boxes are being “leafed through”.

To bound the pivotal movement of the storage boxes 16 in the set-updevice, the base 26 of the present exemplary embodiment comprises atleast two stops 30, 31. Thus, the pivotal movement of each storage box16 is bounded between two inclined positions located on either side ofan imaginary plane P associated with the relevant storage box, whichplane P extends perpendicularly to the surface A on which the base 26 isdisposed or to which the base 26 is connected, and in which imaginaryplane P the imaginary pivot line L of the relevant storage box 16 islocated. In these two extreme pivoting positions, the top and bottomsides 17, 18 respectively of the storage box 16 are perfectly readable.

It is understood that the invention is not limited to the exemplaryembodiments described, but that various modifications are possiblewithin the framework of the invention.
